Abstract
Crop loss due to different biotic and abiotic stresses is an ever-increasing problem worldwide. Salinity especially has destructive effects towards plant growth and development. Therefore, plants must adapt efficient mechanisms to cope with this kind of stress so that their survival would not be threatened. Halophytes have B. Sghaier-Hammami (*) · C.
